To all lwhom t may concern.'

Be it known that we, EDGAR F. HATH- AWAY and CHARLES LEA, both citizensof the United States, and residents of Boston, county of Suffolk, Stateof Massachusetts, (Whose post-office addresses are 195 Freeport street,Dorchester, Massachusetts,) have invented an Improvement in Warp-Leasing Machines, of which the following description, in connection withthe accompanying drawings, is a specificatiom like characters on thedrawings representing like parts.

This invention relates to warp leasing machines intended 'formechanically leasing a warp and more particularly, though notexclusively, a new warp which it is desired to have leased prior to itsinsertion in the loom.

The invention will Ibe 'best understood by reference to the followingdescription when taken in connection with the accompanying illustrationof one specific embodiment thereof, while its scope will be moreparticularly pointed out in the appended claims.

While the various elements of the machine to be described may 'bearranged in other relations than those herein set forth, and while thedetails thereof may be widely varied from those disclosed in the hereinspecic and illustrative form of machine, there is here provided acarriage sustaining a reciprocatory threadplacing device and operatingmechanism therefor, Which carriage is caused to advance @progressivelylengthwise the machine to traverse the warp, the latter being maintainedwith its threads held in substantially parallel arrangement. Theadvancing thread-placing device is caused to seize the foremost Warpthread and place the same lbetween suita'bly ositioned lease members,these being herein in the form of fieXible cords or other flexiblemembers suitably held at their opposite ends upon the frame of themachine.

Means are provided to coperate with the thread-placing device to stripthe drawn thread therefrom and thrust aside the leased threads from theline of action. At snitable times, and ordinarily between successivethread drawin s, the relation of the lease cords is shifte by guidingand holding -devices which are here mounted on the traveling carriage totravel therewith so that in the described machine the successive threadsare left reversely arranged between the lease members.

Referring to the drawings and tothe illus- -trative embodiment of theinvention, there is provided a suitably supported bed or frame 1supported by the legs 2 and carrying the end frame members 3 which serveas supports fof the warp shaft, lease cords and other members.

The war is sustained during the operation of the macrliine in a warpcarriage or holder of any suitable construction, but which herecomprises the end frame members 4 (Figs. 3, 4 and 5) which are connectedby rods 5, 6 and 7 and have the upper and lower clamping jaws 8 and 9,respectively. The carriage is supported by oppositely extended hangerrods 10 resting on roller supports 11 journaled on the frame of themachine (Figs. 3, 4 and 6) and thereby malntainmg the carriage forlongitudinal adjustment lengthwise the machine. The projecting ends ofthe connecting rod 6 are caused by .the weight of the carriage to pressone against a suitably formed guiding portion l2 (Figs. 5 and 6) at oneend of the stationary frame of the machine and the other against a Worm112 (Fig. 4) to be later'described.

The warp threads designated at 13 when positioned in the machine havetheir free ends clamped loosely in the usual clamp bar 14 which isplaced in the upper pair of clamping jaws 8. From the clamp bar 14 thelthreads pass over the thread separator shaft 15 and thence downwardlyand outlwardly to the second clamp bar 16 wherein they are tightly heldand thence down to the loom beam (not shown). The upper l clamping jaws8 are adjustably mounted on the supporting rods 17 so that they may beadjusted toward and from the separator shaft 15 to put the necessarytension u pon the threads over that shaft.

The thread-placing device, herein in the form of a drawing-in needle 20,is mounted upon a carria e 21, the latter being adapted to slide lengtwise the machine and transversely the warp upon suitable guideways 22formed on the bed of the machine. During the travelof the'carriage theneedle is given a reciprocatory movement to and from the threads of thewarp.

The construction of the needle ':arriage, the traversing mechanismtherefor, and the needle operating and thread stripping me. h-

' anism is substantially the same as that shown in prior patent to Fieldet al. No. 871,680, dated November 1, 1907, and need only be brieflyreferred to:

To advance the carriage, the latter is provided with a split nut 23(Figs. 4 and 5) which may be thrown into or outofengagement with thelead screw 24 by means of the hand lever 25. The. lead screw iscontinuoulsly. rotated during the operationof the maehlne for thegradual advance of the carriage from the main drive shaft 25 throughchain transmission devices 'which are shown at the right in Figs. 2and-4, and designated generally by the numeral 26. These may be of anysuitableonstruction, but herein they are of the type described in psntto Lea No. 1,090,401, dated March 17, The drive shaft 25 carries at itsopposite end the loosely journaled driving ulley 27 which-may beclutched to the shaft by means of the sliding clutch member 28, thelatter in turn being operated by the forked lever arm 29, the rock shaft30, upright lever arm 31 and slidingactuator rod 32, the latterextending) the full length of the machine and slidaI l 3 so that themain drive shaft: clutch may be thrown into or out of engagement by theoperator at any point along the machine. A brake band 33 embracing thebrake drum 34 on the main drive shaft is also adapted to be applied orreleased simultaneously with the release or application, respectively,'of the clutch member by meansI of the. brake y mounted in the framemembers lever arm 35 also eonnected'toy Athe rock shaft 30.

` The drive shaft is splined to permit drivilg engagement therewith ofthe gear 36 1g. 5), the latter mounted to slide with the carriagelengthwise the machine and acting to drive the operating mechanismlthereon. The gear 36 meshes with the needle operatin gear 37, whichlatter actsunsv through an intermediate gear 38 and thel crank disk 39and connectin link 40 to move the pivoted arm 41 an the link 42 forreciprocation of the drawing-in needle 20. The latter slides in a sleeveor cylinder 43 and is given a partial turn on its advance and retractionby the engagement of a pin 44 (Fig. 4) upon the needle with a.

partially spiral slot 45 in the sleeve. The

means for selectingand separating the fore- I most warp threads andpositioning a thread in the needle path for each vthread drawing. Hereinsuch thread separating member is in the lform of a sleeve 46 (Figs. 4,13, 14 and 15) splined upon the driving shaft 15. -The shaft 15 isloosely journaled at one end- (Fig. 4)- in the rod 47 held fixed essere@inv the frame of the machine, the .end of thesecured to turn with thesleeve 48, the latter,

journaled in the opposite frame member and driven from the main drivingshaft by means of the intermeshing gears 49 and 50 (Figs. 3 and 6),'-thesprocket wheel 51, connecting sprocket chain 52 and sprocket wheel 53,the latter on the main drive shaft 25.

Referrin to Figs. 13 to 15, inclusive,` the sleeve mem er 46 has acorrugated tapered nose 54 which strokes the threads into par` allelism,this being succeeded by a spirally grooved portion 55, the advancing lipof which picks up the foremost thread and conveys it into the path ofthe needle. lThe spirally grooved sleeve 55 can be angularly adjustedupon the sleeve member 46. For this purpose the sleeve 55 terminates inaflanged portion 56 having a recess in which there is adapted to seatthepin 57 slidably mounted in the collar 58, the'latter being fast to thesleeve 46 by means of the set screw 59 shown in Fig. 15. rIhe'oppositeend of the pin 57 is threaded into a disk 60 which latterl is normallyheld close against the face of the collar 58 by the stud 61. The latterhas one end threaded into the collar, but is provided with a ,head 62sliding in a recess in the collar, a spring being interposed between theheadand the bottom of the recess yieldably to force the collar into theposition shown.

The collar, however, may be drawn to the left, as viewed in Fig. 14,withdrawing the pin 57 Y from the ange of the sleeve 56, whereupon thelatter may be turned, thereby to adjust the lip of the screw or helix indierent angular positions about the shaft. The flange 56 may be providedwith a plurality of recesses distributed circumferentially about thesame to permit of dierent positions of adjustment of the pin 57.

Thecollar 58 is circumferentially grooved as shown in Figs. 13 and 14and rests byl its groove in the hook-shaped bracket 63, which latter iscarried by an arm 64. fastened to an upright supportl 65 (Figs. 4 and 7)fixed on the needle carriage 21, so that the vseparating worm advancesprogressively across the machine always in fixed relation to the needlebut being turned inr suitably timed relation -to present a thread:v foreach thread drawing. The threads when engaged by the needle are drawnbetween suitably osi,-

'tioned lease members. These may be o any each arranged parallel withthe travel of 'I the needle carriage lengthwise-the machine. The ends ofthe cords may be conveniently secured to the' hooks 72, one hook at eachend of the two cords. The construction of leasing cords and .71 areintermittently fthe cordholding and guiding means on the v vibrated to'impart to them a reverse reciprocatory movement so as to place them ater nately above and below the plane of needle action. For this purposethe cords pass through guiding and holding devices carried bythe needlecarriage, herein in the form of guiding eyes 73 formed in theoppositeends of the oscillatory lever arm 74. The latter is at one endof 'a short shaftv l7 5, the opposite end of which carries the inion 76meshing lwith the teeth of the vertically slidable and reciprocatoryrack bar 77. The latter, which is guided for vertical movement` in thelugs 78 and 79 at the side of the support 64, (Fig.7) isnormallydepressed by the coiled spring80 so that, a cam roll 81 lcarriedby the lower forked end of the said chain 83 (Figs. 4 and 5)`whic,h isdrivenfrom a sprocket wheel 84 carried upon the needle carriage shaft 85driven by the gear 37. Rotative movement of the cam 82 which accompaniesthe needle reciprocation causes the vertical vibratory movement of therack 77 and the intermittent oscillatory reciprocation of the swingingarm 74, the timing being such that the guiding and holding eyes arethrown from the full line position shown in Fig. 7 to the dotted lineposition at the end of one needle reciprocation and again to the fullline position at the end of the next needle reciprocation, the two leasecords being therefore thrown alternately to thereof. The result is thatthe two lease members are caused to be alternately der pressed andelevated at or about the path of the needle between successive threaddrawings sothat while positioned as shown in full lines in Fig. 7 on onethread drawing,

they are .subsequently reversed in relation and positioned as shown indotted lines on the neXt thread drawing. They are then `re turned to theposition shown in full lines, this resulting in the positioning Qfsuccessively drawn'threads on opposite sides of the lease cords and theformation of a lease.

In order to move the leased threads away7 fromthe line of action of theneedle and prevent their subsequent crossing over oi' under the needlepath, means are preferably provided for thrupting aside a drawn thread.This is conveniently accomplished herein byproviding-the reciprocatorylease cord holding members themselves with such a forma-tion or withsuch means that their movement automatically tends to thrust the leasedthread aside toward the already leased threads of the w-arp. Herein thisis accomplished by providing thrust members 86 (Fig. 8a) whlch projectfrom the sidesof the arm 74, one above each of the lease cords 70 and71, in the direction opposite to the traverse of the needle carriage.These are curved outwardly and downwardly v and when depressed liedirectly under the needle` path, as is represented in 'Fig. 8. As thedepressed holdlng eye rises toits elevated p`osition the-thread whichhas 'ust before been drawn between the two cor s by the 4needle iswedged to one side (to the right as viewed in Fig. 8) so that assistedby the reversing movement of the lease cords which takes lace at thesame time 'this guard-thrusts the eased thread clear of the path of theneedle. This action is further assisted by means of a thread and needleguiding plate 87 secured to the upright support 6'5 and provided with aneye 88 registering with the path of the needle and with upper and lowerpropections or guards 89 and 90 the lower one of which is curveddownwardly to act asa deflector assisting the deflection of the leasedthread.

To assist in quickly setting up the machine i the lease cord guidingeyes 73, which are substantially parallel with the normal position ofthe lease cords, are provided with lateral openings in the form of slots91 (Fig. 8) which are inclined somewhat to the eye per- Aforation 73.This permits the cords to be quickly inserted through the lateral insertion slots 9d, whereupon they drop into the eyes 73 (assuming thelposition shown in Fig 8a) and are Without any tendency to' the machinewithout any particular regard to its being taut vor under tension, thenatural stiness of the cord insuring its accurate position with respectto the needle as it is held between` the guard 86 and the eye 73. Thisconstruction provides in effect a rigid guiding frame] which. spreadsand guides the cords at the line of needle action and by itsreciprocatory rockin or tipping movement positions the cords a ternatelyand reversely with relation to'the needle path.

The mechanism described will act to draw a single threadleasez that isto say, a lease wherein each successlve thread 1s drawn on oppositesides of a given lease member. Provision, however, is made :for drawingwhen required a two-thread lease, that is to say, one wherein pairs ofsuccessive threads lie upon the same side of a given lease member, thelease cords being reversed as to position only for each alternatevthread drawing.

For this purpose the cam 82 which is shaped. to give one reciprocationlof the leased cord holding arm 74 for each thread drawmg isinterchangeable with a cam 92 So shaped as to give but one reciprocationof the arm 74 for each alternate thread drawing. The cams 82 and 92 aremounted upon a 4stud 93 (Fig. 7a) on which the sprocket wheel 94engaging the sprocket chain 83 has free rotative movement. The cams 82and 92 each has a hole or recess in its Ainner face adapted to receivethe driving pin 93x ixed in and projecting from the outer face of thesprocket wheel 94. In Fig. 7 a the cam 82 is shown as rotatively engagedby the sprocket wheel driving pin 93", but, by removing the headed screw95, the cams Vmay be slid oil' from the stud, their positions reversedand the. cam 92 placed in rotative engagement with the driving pin. Whenthis -adjustment is made, the machineis effective for drawing a twothread lease.

In the -described machine the thread as it is drawn between the leasemembers is also drawn into engagement with suitable members which tendto retain it approximately in its drawn position and prevent theentanglement or disengagement of the leased thread. In the describedmachine this is arranged by providing a series of closely arrangedmemers such as the resilient lbristles 97 (Figs-2, 4 and 5) or the like,the lower ends of which are held fastened on the supporting bar 98secured Ato the frame in such position that the bristles are transverseto the line of needle vaction. This results in causing the free ends ofthe threads to be drawn and laid in the bristles where they are heldwith sufficient certainty to prevent the escape of the leased warp ends.

The free end of the'thread after being withdrawn between the `leasecords and through the bristles is drawn through-the eye 99 of the guardand deliecting plate 100 (Figs. 5 and 5a) back of the line of bristles,the eye having an opening slot through which the thread passes whenstripped by the stripper arm 101. The latter (Figs. 2, 4 and 5) on eachfullretraction of the needle isl caused to' move transversely across theneedle path and strip the free thread from the needle hook, regaining,however, its normal position before the next advance of the needle.Thestripper arm 101 is slidably mounted in a'sleeve 102 pivoted on theframe at 1 03, andA is given a reci rocatory movement like that of aconnectlng rod through Lasarte its connection to the crank disk 4104.The latter, is driven by the shaft 105, turned through the beveled gear106 meshing with the gear 107,'the latter upon the needle drive shaft108 which is turned by the needle drive gear 38. rlhe proportions of thegears are such that the stripper is caused to execute itsstrippingmovement upon each retraction of the needle.

rlhe advance of the drawing needle is proportioned by means of thegearing 26'with close approximation to the spacing of the warp threadsPreferably to 'correct required deviations from the prearranged travelof the needle, there is provided a handl adjustment access-ible to theoperator of the machine for adjusting the entire series of warp threadslengthwise the travel 0f the needle and properly alining the foremostthread thereof with the needle path. For this purpose the overhead. rod32 is suitably journaled for rotative movement in the frame 3 and issplined at one end to the s rocket wheel 109, the latter mounted on a seeve 109x journaled in the frame member 3 and connected by the sprocketchain 110 with the underneath sprocket wheel 111 which is journaled inthe frame of the machine and secured to a worm 112 of large diameter.r1`he latter is caused to engage with suitably formed teeth 113 intheside or face of the adjacent hanger rod of the warp carriage so that onmovement of the- Worm the carriage is given a slight compensatingmovement lengthwise the machine, so

`that the operator can control the same in lany position.

. The described machine is provided with two leasing members to draw latwo cord lease., By a slight adjustment of the machine three leasing`members may be employed and a three cord lease drawn. Such modificationor adjustment ofthe machine is represented in Figs. 9 to 12, inclusive.lin

this machine there is substituted for the rockl arm 74 having the twothread holding eyes a rock arm 114 having but a single thread holdingeye. 115. A second lease cord 116 which moves up and down with the cord115, is controlled by the guiding eye of a similar lever arm 117, thelatter being mounted upon a shaft 118 journaled in the frame support 65and carrying at its opposite end the pinion 119 similar to the pinion 76 on the shaft 75. The vertically movable rod 77 is provided with rackteeth on opposite sides thereof, one set meshing with the pinion 76 andthe other with the pinion 119 so that as it is vibrated verticallyfthetwo arms 114 and 117 are simultaneously swung up or down. A third-in-This controls the lease cord' described and the machine shownin Figs. 9to 12, inclusive, may be converted into the previously described type ofmachine by merely taking of the arm 117, the shaft 118 and gear 119 andsubstituting 'for the arm 117 an arm similar to the arm 74. The resultis that as the rod 77 is vertically reciprocated by the cam 82, themiddle lease cord 120 is vibrated first from below the needle path to apoint above, while the two lease cords 115 and 116 are simultaneouslyvibrated from a level above the needle path to a level below the same,successive threads vbeing placed in reverse relation with reference tothe two sets of lease members.

While we have herein shown and described one form of the invention, itis to be understood that the same is not limited to the details hereinshown, nor to the particular arrangement of operating parts, nor themode of sustaining the warp with reference to the operating elements ofthe machine, but that extensive modifications of the illustrated detailsmay be made and wide departures therefrom followed without departingfrom the spirit of our invention.
